Application filed September V22, `1,927'.y Serial No. 221,205.

The present 'invention relates to improvements in motor driven cars.

More particularly the present invention relates torinspectionl carsadapted to travel upon railroad rails. Such cars have been provided with internal combustion motors, but the vibration which 'has been. set up by said motors as heretofore installed has been very annoying to the passengers on the car and has been destructive 'of the` parts of the motor and the car.

An objectvof the present invention is to provide a motor driven car of the type adaptedto inspection car service in which vibration is reduced to a minimum. p

A further object is to provide 'a car ofthe inspection car typcin which the effects of viv bration are. minimized without the use of expensive cushioning devices. ,y L n A further object is to provide a relatively simple car'of the inspection car type in which vibrations set up by the motor are taken in such a plane that suchvibrations are not communicated tothe-frame ofthe car. y

Further objects will appear as the description proceeds. a n f Referring to the drawings- I Y Figure 1 is a top plan view of a practical 'embodiment ofthe present invention;

Figure 2 is a sectional view taken alongthe plane indicated by the arrows 2 2 of Figure 1,; and l n Figure 3 is a sectional` view taken along the .plane indicated bythe arrowsH3-3 of Figure 2. Y Y

The illustrated embodiment `of the'present invention includes a lframe 10, which may be rectangular in conformation. Said frame l1.() carries bearings 11-*11 for securing-the front 10 axle 12, which may. be al rigid axle. At the l rear of the car are bearings 13-13 adapted to l support the rear axle 14. Railroad Wheels 15 15 are mounted upon thetwo axles re- The rear axleY 14 lis preferably a rotary axle andis provided with power transmitting` mechanism, which will be lreferred to in detail hereinafter. It will .be understood, of course, that if the front axle 12 is a rigid axle, the wheels 15 will bevrotatably mounted upon said axle 12. Inasmuch as the rear axle 14 is preferably va rotatable axle, the wheels 15 associated with the rear axle 14 will be keyed or otherwise secured thereto. The frame 10 is braced from front to rear by a' plurality of fore and aft members 16, 17 and 18, which may take the form of timbers 1 Said. guide membersv have the further funcservice.

Itor 30, the water lines 31,-31 from-the radiaand which mayhave their extremities `bolted or otherwise secured tothe frame 10. The v frame 10 may also be bracedby tie rods 19-19, which may underlie the fore and aft 60 members 16, 17 and 18.V y The fore andaft members 17 and 18 constitute supporting members for the power plant or power unit which will now be referred to. The numeral 2O indicates the power unit platform, which may be constructed of wood and which mayrestdirectly upon the foreand Yaftfmembers 17 and 18. Bolts 21-21 are`V provided for holding the platform 20in predetermined position, which bolts 21 extendthrough slots 22 insaid platform, whereby said platform may be adjusted to, compen-` sate -for chain stretch in a mannerwhichwill be referred to rfurther hereinafter. rlhe power unit platform may be guided by means ofangles 22a-22'LL or equivalent means, whichV angles may be' secured to the platform and which may have bearing engagement with the sidesof the fore and aft members 17 and18.' tion of holding thel parts against warpage in Thepowerfunit preferably consists of a multiple cylinder internal combustion 'engine. In apractical embodiment of the presvent invention such as illustrated in the draw- ,ingsV a two-cylinder, two-stroke cycle motor f has proveneminently satisfactory. The motoi' is indicated as a whole by the numeral 23, and as shown comprises the base 24, which is bolted or otherwise secured vto the platform 20. Said motor 23 lcomprises, the pair of cylinders 25--25,which arepreferably Aco- `axially disposed, the axis of said cylinders being located substantially transversely kof the line of movement of the car, as clearly shown y in Figure 1. The motor 23 is providedwith the fly wheel 26, the carburetor 27,.'the spark control 28, the gasolene tank 29,fthcradiatorl to the cylinders of the motor, and fthe other usual vfeatures of an'internal combustion motor.v y

A salient feature of the presentinvention i yis that the shaft of the motor 23 is disposed 195 'l vertically, or substantially vertically. Thev axis of the shaft of the motor 23 is indicated Y by the Center line 32 in Figure 3. 'Y i The vertical shaft of the motor 23is connected by means of bevel gears (not shown), or other power transmitting' mechanism, to the horizontal jack shaft 33, which is preferin the length of the sprocket chain 37'.

ably disposed transversely of the car; Cooperatively associated Vwith the jack shaft 33 is the clutch 34, which is controlled by the clutch lever 35. y vSaid clutch Bet controls the Connection of the jack shaft 33 with the chain sprocket 36. The sprocket 36 is adapted to communicate power to the chain 37,V

which meshes with the sprocket leyed to the rear aXle 14 of the car.

The function of the ab'ove described apparatus will be clear without detailed explanation.

It will be noted that the power plant is in a single lunit carried by the platform 20, which platform is adj ustably'mounted upon the fore and aft members 17 and 18. By rearson of th-e slotted connection between the platform 2O and the fore and laft members 17 andv 18, said plat-form and consequently the power unit may be adjusted fore and aft of the car, whereby to compensate for changes By reason of the fact that the cylinders 9,5 of the motor 23 are disposed horizontally, the shocks dueto stopping and starting of the pistonsV in saidcylinders are dissipated transversely of the car, whereby aminimum effect i of said shocks is'comniunicated to the frame ofthe car. By reason of thisy construction the amount of cushioning which is necessary to protect the parts against the crystallizing effects of vibration is reduced to a minimum.

A As a matter offact, the cushioning effect of the timbers comprising the fore and vaft members 17 and 18 is sufficient in a practical embodiment of the present invention 'to take Vcare of the small vibration which'is con munie-ated to said timbers bythe motor.

Y Practical operation hasV demonstrated Vthe [fact thatv the only time that vibration is conilwhereby it is unnecessary in making adjustments to provide flexibley connections or flexi'ble joints. A further decided practical advantage accrues when the deviceris being shipped, as for example onl shipboard.

There-isV va vdecidedly practica-l advantage in removing the power plant from the frame 10 and-cleating the power plant directly to the crate. Moreover, when a plurality of the'devices are being shipped by freight, a plurality of power plants may be nested together, reducing bulk to a minimum. Stillanother decided practical advantage is 4that the vready Vremovability and replaceability of the power plant permits a power plant to be taken from its frame and put in the shops for repairs ork adjustment, a reserve power plant 'being mounted upon the frame while'the first one is being serviced.k vIt will be notedV that tlie sembly and disassembly of the/'power plant relative to the base is a very simple matter well within the skill of the ordinary worker.

Though a preferred embodiment of the present invention has been described in detail, many `modifications may be made without departing' from the spirit of the invention. It is intended to cover all such modilications that fall withinv the scope of theap-A nal combustion 4motor for communicating;l power to said wheels, said motor having twov opposed cylinders having their axes coaxially" disposed transversely of the line .of movefr ment of said car, said motor having its'power transmitting shaft disposed in a'substantially vertical position. V

In a car of the type described, a frame, wheels for supporting said frame, an internal combustion motor for communicating power to said wheels, said motor'having a kpair Vof cylinders jcoaxially disposed Vtransverselyvof saidcar, a vertical shaft for delivering power from 'said cylinders, a j aclr'shaft disposed transversely of said car, power."
